The Genus Sanicula in the eastern United States, with Descriptions 
of two new species. 
By EvuGENE P. BICKNELL. 
(PLATES 241-245.) 
It has been generally received as a settled fact of our geogra- 
phical botany that the genus Sanicula had but two representatives 
in the flora of eastern North America. These plants, S. Mary- 
landica and S. Canadensis, though coming down to us as well- 
accredited species from the time of Linnaeus, have proved a recur- 
ting source of confusion to our botanists and, as now appears, 
have never been rightly understood. In 1824 Dr. Torrey reduced 
Canadensis to a variety of Marylandica (F\. U.S. 302), and in 1838 
Torrey & Gray (Fl. N. Am. 1: 602) discredited the plant altogether 
naming it as a synonym of the latter species. A few years later, 
however, Dr. Torrey took occasion to restore the plant to its 
Original status, remarking that he had become persuaded that the 
two species were quite distinct (Fl. State of N. Y. 1: 265); not- 
withstanding this, recent authorities have reverted to Dr. Torrey’s 
€arlier view. In the “Review of North American Umbelliferae, 
Coulter & Rose” (1888), S. Canadensis finds recognition only as a 
Slightly differentiated form of S. Marylandica, a disposal of the 
Plant which is followed in the sixth edition of Gray’s “ Manual”
